Description

Devices for evacuating people from lift cars

The present invention relates to an apparatus for evacuating a person from an elevator car, an elevator system including such an apparatus, and a method of evacuating a person from the elevator car.

The elevator system includes at least one elevator car arranged in the elevator hoistway so as to be able to move vertically along the guide rails, generally for conveying people or goods between the two floors. This type of elevator system is continuously maintained during operation to ensure the safety of the person being transported and the elevator system. Nevertheless, the elevator installation operation may be interrupted due to external influences of the elevator installation or defective parts. For example, interruption of the safety circuit of a power outage, lightning or elevator system can cause the elevator car to be sandwiched between the two floors, together with the moving people therein. Therefore, people isolated in the elevator car need to evacuate from the elevator car.

JP2005-154025A discloses a evacuation device for evacuating a person when two elevator cars are arranged to move sideways from each other in an elevator hoistway in normal operation. When the first elevator car of the two elevator cars is isolated from the elevator hoistway, the second elevator car is positioned next to the first elevator car. Evacuation passages of two elevator cars facing each other can be opened. These evacuation passages may be connected by a sidewalk or evacuation sidewalk, and the evacuation sidewalk may be secured at the lower boundary of each evacuation aisle. To evacuate from the first elevator car, evacuees cross the evacuation route to reach a second elevator car that can still move.

In order to fix the guide rails of the two elevator cars, it is common to arrange the fixed supports extending horizontally between the moving paths of the two elevator cars at regular intervals. The disadvantage is that, when escaping from the first elevator car, this type of fixed support can prevent the escapee from reaching the second elevator car without any obstacles when passing over the walkway. This is the case where the fixed support is located directly in front of the escape passage.

Therefore, a problem to be solved by the present invention is to increase the safety of a person who evacuates from an elevator car.

The problem is solved by an apparatus for evacuating a person from an elevator car, the apparatus preferably comprising an elevator car, a tread element defining a lower end of the escape passage in the elevator car, A sidewalk comprising an end portion, the sidewalk including the sidewall, which can be attached, preferably hinged, to the tread element by the first end, the device comprising at least one Wherein the crosspiece is designed / used as a step, and wherein the first end of the sidewalk is alternatively attachable or removable on the crosspiece other than on the tread element.

This problem is also solved by an elevator system including this type of device.

This problem is also solved by a method of evacuating a person from an elevator car comprising this type of device, wherein the first end of the sidewalk is attached or hooked to the crosspiece.

This type of evacuation passage is the opening of an elevator car provided to evacuate a person, for example a side wall of an elevator car or a handrail disposed on a car roof. During normal operation to transport a person, the person to be transported can not pass through this type of evacuation opening.

The present invention is based on the knowledge that the evacuation from the level of the car floor of the elevator car to be evacuated can be very difficult due to the existing vertical position of the fixed elevator car to be evacuated in the elevator hoistway. This is due to the fixed support for the guide rails or other elements arranged in the elevator hoistway, which can be arranged directly in the escape passage of this fixed elevator car, i.e. a substantially stationary car in the vertical direction. However, it is desirable that the fixed supports or elements do not hinder this sort of evacuation to constitute an obstacle for the person to evacuate.

To achieve this, the evacuation opening for evacuating a person is altered so that the vertical height of the sidewalk, which can be placed on a fixed elevator car for evacuation from a fixed elevator car, can be adapted to the conditions in the elevator hoistway. Thus, the device comprises at least one crosspiece that can be fixed to the escape passage, to which a sidewalk, that is to say a retractable sidewalk, can be attached. Thus, the sidewalk can be placed at different height positions in the escape passage of the elevator car or the elevator car to evacuate. If necessary, the top rim at which the sidewalk can be advantageously secured for evacuation under given circumstances is a relatively large distance from the tread element. In this case, at least one additional crosspiece may be disposed between the topmost crosspiece and the tread element. To meet the relevant safety requirements, at least one handrail may be secured to the sidewall in its longitudinal direction. This type of handrail can minimize the risk of people falling into the elevator hoistway when crossing the sidewalk.

An improvement of the device includes a bar attached to the elevator car by the escape passage, it being possible to attach at least one crossbar to the bar. This type of bar permits a fixed spacing between at least one safety crosspiece and tread element and thus increases the safety when passing through the escape device.

The device may include a second bar, which may be secured to both sides of the escape passage in the elevator car, and at least one cross bar may be attached to the second bar. This type of second bar makes it possible to securely secure all the crossbars on both sides of the escape passage.

In an improvement of the device, the bar (s) are arranged perpendicular to the tread elements. This allows the device to be placed in the elevator car in a simple and compact manner.

The bar may be part of the railing disposed on the car roof of the elevator car. Evacuation through the car roof of the elevator car to be evacuated is an option for evacuating people from the inside of the elevator car or from the elevator car to evacuate. For example, it is possible to reach the escape passage by leaving substantially vertical from the interior of the elevator car onto the corresponding car roof. For example, during a maintenance operation performed by a service technician on a car roof, the evacuation opening in the handrail can not be preferably passed.

Alternatively, the bar (s) may be disposed on both sides of the escape passage formed as a escape door. This type of escape door can be placed directly on the side wall of the elevator car. Therefore, the person to evacuate can directly enter the sidewalk from the inside of the elevator car. During normal operation for transporting a person, the person to be transported can not pass through this type of evacuation opening formed as a evacuation door.

An example of an improvement of the device comprises a safety barrier comprising a safety contact which can be arranged in the escape passage such that the safety barrier blocks the escape passage at its fixed position and the safety contact is closed only at the fixed position of the safety barrier do. In order to allow a person to start safely from the elevator car to be evacuated, the evacuation passage is opened only when the safety contact is opened, that is, when the safety circuit is opened. Only when the safety circuit is closed can the elevator car be moved by the service technician, if necessary. Preferably, the safety circuit of the elevator car in which the removable safety barrier is arranged can be opened by removing this safety barrier.

Preferably, the safety barrier is in the form of a rod and may be attached on at least one crossbar. In this way, regardless of the position of the crossbar to which the sidewalk is attached, the escape passage is always shut off when the safety barrier closes the safety contact.

In another embodiment, the safety barrier can substantially completely close the escape passage at its fixed position. For example, this type of safety barrier that closes the escape passage at the fixed position may be formed by the door leaf of the escape door at the closed position. In this way, the safety of the person to evacuate can be enhanced.

The improvement example of the elevator system comprises an additional elevator car, the further elevator car comprising an additional evacuation passage assigned to the additional elevator car, and the evacuation passage of the elevator car and the evacuation passage of the further elevator car, You can connect. Thus, an additional, i.e. second, elevator car can be placed substantially next to the elevator car to be evacuated. Preferably, the two escape passages of the two elevator cars face each other. When passing through the sidewalk, a person can leave the trapped elevator car and enter the working elevator car.

In an improvement of the elevator system, the lower end of the escape passage of the further elevator car is defined by the second tread element, and the sidewalk can be attached, preferably hung on the tread element by its second end, The additional crosspiece may be designed / used as a step, and the second end of the footway may alternatively be attached or hung to the crosspiece rather than the tread element. It is advantageous if the additional, i. E. The second elevator car is caught in the elevator hoistway, that the person can escape by the first elevator car.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

1 shows an elevator car hung in an elevator hoistway and shows an elevator system including a device for evacuating a person.
Figure 2 shows an escape passage disposed in one of the side walls of the elevator car and formed as a escape door.
Figure 3 shows the escape passage arranged on the car roof in the form of an integral part of the railing.
Figure 4 shows an elevator system including an apparatus for evacuating persons from an elevator car.

Fig. 1 shows an elevator car 5 of an elevator system engaged in an elevator hoistway 2. Fig. The elevator hoistway 2 is adjacent to two floors 10.0 and 10.1, one of which is disposed directly above the other. Each of these floors 10.0, 10.1 has shaft doors 11.0, 11.1. During normal operation, when the elevator car 5 is not caught, the elevator passengers are guided by the shaft doors 11.0, 11.1 where the elevator car 5 is located and the car door 6 of the elevator car 5, It is possible to enter and exit the elevator car 5 through the elevator car 5.

When the elevator car 5 is caught in accordance with Fig. 1, one of the floors is disposed between two floors 10.0 and 10.1 arranged directly above the other. This means that the interior of the elevator car 5 can not be reached through one of the shaft doors 11.0, 11.1 from one of the floors 10.0, 10.1. Instead, in the same way, the elevator car 5 may be equally arranged in one of the shaft doors 11.0, 11.1, while the shaft doors 11.0, 11.1 in which the elevator car 5 is disposed, (6) is caught in the closed position. Thus, people inside the elevator car 5 can not leave the elevator car 5 either through the car door 6 or through one of the shaft doors 11.0, 11.1.

In order to be able to evacuate passengers inside the elevator car 5, the elevator car 5 includes a escape passage. For example, an outlet from the elevator hoistway 2 can be reached through this escape passage of the elevator car 5. [

The escape passage is formed as the escape door 20. This type of escape door 20 is disposed in one of the side walls 8 of the elevator car 5 and is provided only from the outside so as to safely evacuate a person from the elevator car 5, Can be opened.

Alternatively or additionally, the elevator car 5 may comprise an escape passage disposed on the car roof 7 of the elevator car 5. [ This type of escape passage arranged in the car roof 7 can be reached through the roof hatch 30 of the car roof 7 by means of a ladder which can be temporarily disposed, for example, in the elevator car 5. [

Fig. 2 shows an escape passage formed as one of the escape doors 20 and disposed in one of the side walls 8 of the elevator car 5. Fig. 3 shows a part of a device for evacuating a person, this part being formed as an integral part of a railing 15 disposed on a car roof 7.

The parts of the apparatus for evacuating persons are disposed in the evacuation passages shown in Figs. The lower end of the escape passage is defined by the tread element 46 of the device. The tread element 46 can be used as a first step for entry or it can be used to hang or attach to a sidewalk, i.e., the escape passage (not shown in FIGS. 2 and 3). The apparatus includes at least one crossbar (47.0, 48.0, 49.0), and the crossbar (47.0, 48.0, 49.0) may be attached over the tread element (46). The top element of the elements attached to the evacuation passageway during evacuation, including at least one crossbar (47.0, 48.0, 49.0) and tread element (46) attached, is used to attach the sidewalk during evacuation. Preferably, these elements, one of which is disposed directly on the other, have a vertical spacing of 20 to 30 cm, preferably 26 cm.

A bar 45 may be disposed next to the door opening such that the at least one crossbar (47.0, 48.0, 49.0) can be placed in the escape passage. The bar 45 includes a fixed area 47, 48, 49 assigned to the associated crossbar 47.0, 48.0, 49.0 for attaching the crossbar (s) 47.0, 48.0, 49.0 in the escape passage. A vertically oriented bar 45 on the tread element 46 may be attached to the side wall 8 or the railing 15 of the elevator car 5 including the escape passage so that the part of the door frame, (15) is formed by the bar (45) for the escape passage.

Accordingly, the second bar 45 'may be disposed on the other side of the escape passage with respect to the first bar 45 and may be formed in the same manner as the first bar 45. Thus, the second bar 45 'includes a fixed area 47', 48 ', 49' assigned to the associated crossbar 47.0, 48.0, 49.0 to attach the crossbar 47.0, 48.0, 49.0, The stationary areas 47 ', 48', 49 'are preferably arranged such that the crossbars 47.0, 48.0, 49.0 are oriented horizontally in the escape passage.

In addition, the safety barrier 52 is disposed in the escape passage, so that the escape passage is blocked even though the escape door or the railing 15 is opened. The safety barrier 52 shown in Figures 2 and 3 is in the form of a rod. The safety barrier 52 providing an obstruction is placed over all the fixed areas 47, 48, 49, 47 ', 48', 49 'of the device that can be assigned to the crosspiece 47.0, 48.0, 49.0 and / To the bar (45, 45 '). The safety barrier 52 includes a safety contact 53 in which the safety barrier 52 is preferably closed at the position where it obstructs the escape passage. When the safety barrier 52 is removed, the safety contact 53 is activated, and thus the evacuation passage is opened. The safety contacts 53 may be integrated, for example, in the safety circuit of an elevator system, and the open circuit prevents the elevator car, to which the safety circuit is assigned, from moving.

The tread element 46 shown in FIG. 2 is preferably disposed above the plane of the car floor 9 of the elevator car 5 so that the car floor 9 resembles the bottom of the trough.

Figure 4 shows an elevator system including a first elevator car 5.1 and a second elevator car 5.2 with two elevator cars 5.1 and 5.2 being located within the common elevator hoistway 2, . The first and second elevator cars 5.1, 5.2 include escape doors 20.1, 20.2. The first escape door 20.1 assigned to the first elevator car 5.1 and the second escape door 20.2 assigned to the second elevator car 5.2 face each other. An apparatus as shown in Fig. 2 for evacuating a person may be disposed or disposed in each of the two escape doors 20.1, 20.2, as shown in Fig. Alternatively, the device as shown in Fig. 3 may be placed in the respective railing of two elevator cars.

Thus, the first of the two devices is placed on the first escape door 20.1, and the second of these devices is placed on the second escape door 20.2. A plurality of fixed supports 60.1, 60.2 arranged one above the other are arranged in the elevator hoistway 2 between the moving paths of the two elevator cars 5.1, 5.2. A rail (not shown) for vertically guiding the elevator cars 5.1, 5.2 in the elevator hoistway 2 may be fixed to this type of fixed support 60.1, 60.2.

For example, the first elevator car 5.1 may be confined in the elevator shaft 2 while the second elevator car 5.2 may still be vertically movable. This means that the first elevator car 5.1 can not move vertically and consequently people inside the first elevator car 5.1 need to evacuate. The first elevator car 5.1, which is trapped in this manner, is particularly susceptible to damage caused by faulty elevator-door contacts, thunderstroke or power interruptions, which open the safety circuit, even though the elevator door including the elevator- . Thus, the second elevator car 5.2 can be elevated so that a person can escape from the first confined elevator car 5.1 into the second elevator car 5.2 via the sidewalk 55, which can be attached to the two devices. Can be located in the hoistway 2.

The first end of the sidewalk 55 is attached or snagged on the crossbar 48.01 of the first of the two devices and the second end opposite the first end of the tread element 46.2 , So that the distance on the sidewalk 55 across which the person to escape will cross is kept as short as possible. Since a person must cross or jump over the lower support 60.1 of the two fixed supports shown in Fig. 4 when crossing the sidewalk 55 (which may entail a high risk of a person falling into the elevator shaft 2) ), It will be understood that this crossing distance may be limited regardless of the vertical position of the second elevator car 5.2 if the sidewalk 55 is attached to or caught by the tread elements 46.1, 46.2 of the two devices .

This means that the second elevator car 5.2 with respect to the first confined elevator car 5.1 may be located in the elevator hoistway 2 for evacuation depending on the position of the fixed support 60.1 which hinders evacuation. Once the second evacuation door is open, the service technician evacuating the person may remove the safety barrier 52.2 of the second device to open the safety contact assigned to the second elevator car 5.2 or to block the assigned safety circuit can do. Further, the safety of the safety barrier 52.2 is controlled such that the safety circuit allocated to the first elevator car 5.1 is blocked so as to reliably prevent the first elevator car 5.1 from moving when the power cut-off ends, for example. It is possible to design the contact portion. If necessary, the first end of the sidewalk 55 may be attached or attached to one of the crossbars 47.01, 48.01, 49.01 attached within the escape passage or onto the tread element 46.1. A crossbar 49.01, which may be affixed on the first end of the attached sidewalk 55 if necessary, is provided to allow a person to cross an additional obstacle which may be constituted by this type of crossbar 49.01, Should be removed to avoid that. A crossbar 47.01, which may be attached underneath the first end of the attached or caught sidewalk 55, may be attached within the escape passage so that evacuees can easily cross the sidewalk 55. [

The following described method for evacuating a caged elevator car 5.1 is applicable to both the elevator installation including only the first elevator car 5.1 which is confined and the elevator installation including also the second elevator car 5.2 . In order to perform the evacuation from the first elevator car 5.1, the service technician must switch the trapped elevator car 5.1 to the stop mode. This means that a trapped condition, which may have been caused by a power cut or a lightning strike, is secured. This can be done, for example, by operating the master switch in the machine room of the elevator installation. Thus, the trapped elevator car 5.1 is prevented from moving by restoring the power supply externally, so that the service technician working outside of the trapped elevator car 5.1 will suddenly restart the moving elevator car 5.1, You can not be surprised or at risk.

The service technician can then access the trapped elevator car 5.1 again. If necessary, the service technician preferably allows the second elevator car 5.2 to be located in the elevator hoistway 2, so that the person can, through the sidewalk 55, which can be attached to the two elevator cars 5.1, 5.2 Moves the second elevator car (5.2) to the service mode so that it can escape from the trapped elevator car (5.1) into the second elevator car (5.2). Once the service technician secures the sidewalk against the risk of a person falling into the elevator hoistway 2, the service technician can remove the safety barrier 52.02 that may be provided on the second elevator car 5.2. The service technician can then place the first end of the sidewalk 55 in the first elevator car 5.1, the tread element 46.1 or the one of the crossbars 47.0, 48.0, 49.0 of the apparatus, As shown in FIG. The second end of the sidewalk 55 may preferably be attached or hung on the tread element 46.2 attached to the second elevator car 5.2. Alternatively, the second end may likewise be attached or hung on one of the crossbars 47.02, 48.02 attached to the second elevator car 5.2. The second end of the sidewalk 55 is attached to the elevator exit of the elevator hoistway 2 if at least it is not possible to escape to the second elevator car 5.2 that can be provided by the person in the first elevator car 5.1 . The safety barrier 52.1 may then be removed so that the sidewalk 55 can be accessed by the person to evacuate and the evacuation can be performed.

In the same way, the equipment provided in the elevator system described in accordance with FIG. 4 is equally suitable for evacuating persons inside the trapped second elevator car 5.2 to the first movable elevator car 5.1.
